Abstract
The present paper focuses on a study model of a trithermal absorption machine, operating at H2O/LiBr couple, powered by a planar solar collector. Therefore, the mathematical model is based on the principles and laws of thermodynamics as well as the heat and mass transfer equations, expressed for the refrigeration cycle. In fact, the results of the complete numerical simulation of the machine, developed within the framework of this study, allow predicting the performances of this type of installation according to the various parameters as well as the operating temperatures and the flow rate in the absorber.
